Upright paper towel holder

Abstract

An upright paper towel holder includes a base, a main body, an elastic body and a lift head. The main body has a lower end portion, an upper end portion and a mounting portion. The lower end portion is connected to the base such that the main body is erected on the base. The mounting portion is connected to the upper end portion. The elastic body is disposed on the mounting portion. The lift head is disposed on the mounting portion of the main body and is capable of reciprocating movement relative to the main body. The lift head is located above the elastic body. When the lift head is pressed down, the lift head abuts against the elastic body, such that the height of the elastic body is decreased, the outer diameter of the elastic body is increased, and the roll of paper towels is securely fixed.
